I haven't made negatives as large as the ones Katharine describes, but
I've added "annexes" in various proportions, even a different material
(eg, a vellum extension of a lith negative). What worked for me was
avoiding straight edges in favor of irregular borders, if possible along
image lines. Then, if necessary, a few delicate strokes of touch up with
colored pencil or matching paint on a small brush and the join becomes
just about invisible.
